Description

Technical Field

[0001] This utility model relates to the field of electroencephalogram (EEG) sensor technology, specifically a bilateral monitoring EEG sensor. Background Technology

[0002] An electroencephalogram (EEG) sensor is a device used to monitor brain electrical activity. It primarily assesses the brain's physiological state by collecting and analyzing EEG signals. EEG sensors typically consist of multiple electrodes attached to the scalp to collect these signals. Sensors can be categorized into dry and wet electrodes. Dry electrodes do not require conductive adhesive and can be directly attached to the scalp to acquire signals, while wet electrodes require conductive adhesive to enhance signal transmission. With advancements in artificial intelligence, neurobiology, and sensor technologies, EEG sensors are gradually becoming a part of our lives. To improve the efficiency of brain activity monitoring, a new type of EEG sensor is needed. However, existing EEG sensors still have the following shortcomings:

[0003] When using existing EEG sensors, most of them connect the electrode pads through a single straight line segment. This makes it inconvenient to adjust the connection length of the electrode pads according to the needs of use, which limits the use of EEG sensors and can easily affect the monitoring results. This leads to a decrease in the practicality and efficiency of EEG sensors. Utility Model Content

[0004] The purpose of this invention is to provide a bilateral monitoring electroencephalogram (EEG) sensor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bilateral monitoring EEG sensor, comprising a connector, an arc segment, and a straight segment. A connecting plate is connected to the middle of the outer side of the connector, and the front end of the connecting plate has an arc segment. An installation docking groove is formed inside the front end of the arc segment, and receiving grooves are formed on both sides of the installation docking groove. A spring damping rod is installed inside the receiving groove, and a limit ball is installed at the front end of the spring damping rod. An installation docking block is connected inside the installation docking groove, and limit through holes are formed on both sides of the installation docking block. A straight segment is connected to the front end of the arc segment, and an electrode plate is installed at the front end of the straight segment. A PCB circuit board is provided at the lower end of the electrode plate, and a conductive paste layer is added to the outer side of the lower end of the electrode plate. Release paper is provided at the lower end of the conductive paste layer, and an auxiliary film block is added to the middle of the outer side of the release paper.

[0006] Furthermore, the internal dimensions of the mounting docking groove are adapted to the external dimensions of the mounting docking block, and the mounting docking block is embeddedly connected to the arc segment through the mounting docking groove.

[0007] Furthermore, the spring damping rod is embedded in the receiving groove, and the spring damping rod is fixedly connected to the receiving groove by an adhesive.

[0008] Furthermore, the spring damping rod and the limiting ball are distributed perpendicularly, and the limiting ball is elastically connected to the receiving groove through the spring damping rod.

[0009] Furthermore, the number of spring damping rods is set to four, and two spring damping rods form a group, and each group of spring damping rods is symmetrically arranged on both sides of the inside of the arc segment with respect to the front central axis of the arc segment.

[0010] Furthermore, the external dimensions of the limiting ball are adapted to the internal dimensions of the limiting through hole, and the limiting ball is connected to the mounting docking block through the limiting through hole.

[0011] Furthermore, the PCB circuit board and the electrode sheet are embedded in each other, and the PCB circuit board and the electrode sheet are fixedly connected by an adhesive.

[0012] Furthermore, the outer side of the conductive paste layer is horizontally distributed with the outer side of the release paper, and the lower surface of the conductive paste layer is closely attached to the upper surface of the release paper.

[0013] This invention provides a bilateral monitoring electroencephalogram (EEG) sensor, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of the spring damping rod, enables the limiting ball to elastically connect with the receiving groove when using a bilateral monitoring EEG sensor. The mounting docking groove, together with the mounting docking block, limits the straight segment to be installed at the front end of the arc segment. At the same time, the limiting ball, together with the limiting through hole, fixes the mounting docking block inside the mounting docking groove, thereby completing the docking installation of the straight segment and the arc segment. Furthermore, it allows for the quick replacement of straight segments of different lengths according to usage needs, improving the flexibility and dynamism of the EEG sensor usage process.

[0015] 2. This utility model, through the setting of a conductive paste layer, enables the capture and recording of electrical signals from the brain via electrodes positioned at the front end of the linear segment when using a bilateral EEG sensor. Simultaneously, the signals are transmitted, processed, and controlled via a PCB circuit board. The conductive paste layer at the lower end of the electrodes reduces the contact impedance between the electrodes and the skin, thereby improving signal quality. The conductive paste layer also adheres the electrodes to the scalp, and release paper protects the conductive paste layer before the device is used. An auxiliary membrane block increases the ease of peeling off the release paper, thus improving the overall practicality and efficiency of the EEG sensor. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 2As shown, a bilateral monitoring EEG sensor includes a connector 1, an arc segment 3, and a straight segment 10. A connecting plate 2 is connected to the middle of the connector 1, and the front end of the connecting plate 2 has an arc segment 3. An installation docking groove 4 is formed inside the front end of the arc segment 3. Receiving grooves 5 are formed on both sides of the installation docking groove 4. A spring damping rod 6 is installed inside the receiving groove 5, and a limit ball 7 is installed at the front end of the spring damping rod 6. An installation docking block 8 is connected inside the installation docking groove 4, and limit through holes 9 are formed on both sides of the installation docking block 8. The internal dimensions of the mating groove 4 are adapted to the external dimensions of the mounting mating block 8, and the mounting mating block 8 is embeddedly connected to the arc segment 3 through the mounting mating groove 4. The spring damping rod 6 is embeddedly connected to the receiving groove 5, and the spring damping rod 6 is fixedly connected to the receiving groove 5 by adhesive. The spring damping rod 6 and the limiting ball 7 are distributed perpendicularly, and the limiting ball 7 is elastically connected to the receiving groove 5 through the spring damping rod 6. There are four spring damping rods 6, and two spring damping rods 6 form a group. Each group of spring damping rods 6 is aligned with the front centerline of the arc segment 3. The limiting ball 7 is located on both sides inside the arc segment 3. The external dimensions of the limiting ball 7 are adapted to the internal dimensions of the limiting through hole 9. The limiting ball 7 is connected to the mounting docking block 8 through the limiting through hole 9. The spring damping rod 6 is fixedly installed in the receiving groove 5 opened at the front end of the arc segment 3 with adhesive. The limiting ball 7 is fixedly installed at the front end of the spring damping rod 6 with adhesive. The spring damping rod 6 makes the limiting ball 7 and the receiving groove 5 elastically connected. The internal dimensions of the mounting docking groove 4 opened at the front end of the arc segment 3 are matched with the external dimensions of the mounting docking block 8 added at the rear end of the straight segment 10. The dimensions are compatible, so the straight segment 10 is limited and installed at the front end of the arc segment 3 by the installation docking groove 4 and the installation docking block 8. At the same time, the internal dimensions of the limiting through holes 9 opened on both sides of the installation docking block 8 are compatible with the external dimensions of the limiting ball 7. Thus, the installation docking block 8 is fixedly installed inside the installation docking groove 4 by the limiting ball 7 and the limiting through holes 9, thereby completing the docking installation of the straight segment 10 and the arc segment 3. Furthermore, it is possible to quickly replace the straight segment 10 of different lengths according to the needs of use, thereby improving the flexibility and dynamism of the EEG sensor in use.

[0022] like Figure 1 and Figure 3As shown, the front end of the arc segment 3 is connected to a straight segment 10, and an electrode plate 11 is installed at the front end of the straight segment 10. A PCB circuit board 12 is located at the lower end of the electrode plate 11. A conductive paste layer 13 is added to the outer side of the lower end of the electrode plate 11. Release paper 14 is located at the lower end of the conductive paste layer 13, and an auxiliary film block 15 is added to the middle of the outer side of the release paper 14. The PCB circuit board 12 and the electrode plate 11 are embedded together and fixedly connected by an adhesive. The outer side of the conductive paste layer 13 and the outer side of the release paper 14 are horizontally distributed, and the lower surface of the conductive paste layer 13 is tightly adhered to the upper surface of the release paper 14. The straight segment 10... The electrode pads 11 at the front end capture and record electrical signals from the brain. Simultaneously, the PCB circuit board 12 transmits, processes, and controls the signals, ensuring accurate signal transmission between components. The conductive paste layer 13 at the lower end of the electrode pads 11 reduces the contact impedance between the electrodes and the skin, while improving signal quality, further protecting the skin and ensuring smooth current transmission. The conductive paste layer 13 adheres the electrode pads 11 to the scalp, and release paper 14 protects the conductive paste layer 13 before the device is used. The auxiliary membrane block 15 increases the ease of peeling off the release paper 14, improving the overall practicality and efficiency of the EEG sensor.

[0023] In summary, when using this bilateral monitoring EEG sensor, the connector 1 is first inserted into the corresponding lead wire interface of the anesthesia depth detection device. The connecting plate 2, in conjunction with the anesthesia depth detection device, reads information from the PCB circuit board 12 and transmits the data. The spring damping rod 6 elastically connects the limiting ball 7 to the receiving groove 5. The mounting docking groove 4, in conjunction with the mounting docking block 8, limits the straight segment 10 to the front end of the arc segment 3. Simultaneously, the limiting ball 7, in conjunction with the limiting through hole 9, fixes the mounting docking block 8 inside the mounting docking groove 4, thus completing the docking installation of the straight segment 10 and the arc segment 3. Furthermore, it allows for quick replacement of straight segments 10 of different lengths as needed. The electrode 11 at the front end of the straight segment 10 captures and records the electrical signals of the brain. At the same time, the PCB circuit board 12 transmits, processes and controls the signals to ensure accurate transmission between components. The conductive paste layer 13 at the lower end of the electrode 11 reduces the contact resistance between the electrode and the skin and improves the signal quality, further protecting the skin and ensuring smooth current transmission. The electrode 11 is attached to the scalp by the conductive paste layer 13, and the release paper 14 protects the conductive paste layer 13 before the device is used. The auxiliary membrane block 15 increases the ease of peeling off the release paper 14, improving the overall practicality and efficiency of the EEG sensor.
